10K Gold is an alloy made of 41.7% pure gold and 58.3% other metals, such as copper and silver. This combination gives it strength and durability, making it suitable for everyday jewelry. The "10K" designation indicates the gold content, with higher karat numbers representing more gold. Due to its lower gold content, 10K Gold is generally more affordable than higher karat options like 14K Gold or 18K Gold. It also has a slightly different color, often appearing more yellow or rose, depending on the metals used in the alloy.
